I just stumbled on the grimmest reddit user profile: it's a working mom raising young kids, with a spouse who suffered a major brain injury that has robbed him of most executive function, and this mom is hanging out on subreddits for things like tCDS, nootropics, and lots of similar treatment-hacking. Now the husband is using the tCDS and I have this Beckett-like image in my mind of a family where the traumatized parents are electrifying each other's brains out of desperation. Just truly grim.
